Calendar invite sender address?

I have a microsoft account in form <name> at <myowndomain.com>. If i send email in outlook the sender adress is  <name> at <myowndomain.com> as expected. However, when i send a calendar invite the outlook invite shows as sender outlook_<lotsofcharacters>@outlook.com and it is impossible to respond to this address (bounces back). How can i change the calendar invites to show mailto:email address removed for privacy reasonsas sender like i can do in email?
